A brass or zinc body under a plated finish — the finish is what you live with day to day, not the metal underneath it. The color is filed as Stainless. It comes undermount.
Undermount openings are cut and polished in our shop off the template, not freehanded in your kitchen. It is one of 8 colors we stock from the Double Bowl Kitchen Sinks range.

How it meets the countertop
The mount type decides what we cut, and what you see every day.
It mounts under the countertop. Practically that means we cut the opening to the bowl and polish the exposed edge — an undermount leaves the stone itself as the visible border, so that edge is finish work, not a rough cut hidden under a rim. The payoff is the one everybody notices: you can wipe the counter straight into the sink.

Size, depth, and the cabinet under it
The numbers off its own spec line, and what each one constrains.
Size
Figure on a base cabinet of at least 36" — the rule of thumb is bowl width plus about three inches for the cabinet sides. We measure your actual run at template rather than trusting the rule.
- 31 1⁄2"x20 1⁄2"
Two bowls
Split into two bowls, so the dimension above is the outside of the pair rather than the space you get for one pan. That is the whole argument between one bowl and two — a divider buys you separation and costs you the ability to lay a baking sheet flat.

Questions about 18G 60/40 - 3120S
Answered from this fixture’s own catalog attributes — nothing generic.
How does 18G 60/40 - 3120S mount?
Undermount. The bowl hangs below the countertop and no rim breaks the deck, so crumbs go straight over the edge instead of catching on a lip. The counter carries the weight, which is why this style wants a fabricated stone top — we polish the cutout and clip the sink to the underside as part of the same job. This one measures 31 1⁄2"x20 1⁄2" across, so it wants a 36" base cabinet.
How many bowls does 18G 60/40 - 3120S have?
Two, and deliberately unequal — a 60/40 split. The large side takes the pans, the small side takes the disposal and the quick rinses. It is the layout that reads as a compromise on paper and works better than an even split in a real kitchen. The pair measures 31 1⁄2"x20 1⁄2" across, so it wants a 36" base cabinet.
What is 18G 60/40 - 3120S made of?
Sheet stainless, formed at 18 gauge. It is the only sink material in this catalog you can put a hot pan straight into without thinking about it, and the only one that will not chip. What you trade for that is a surface which records small scratches — and then stops, once they even out into a finish of their own. On a bowl this wide the gauge is doing real work — there is a lot of unsupported span under your hands, and it is the difference between a sink that feels solid and one that gives.
